A gigantic project to save Antarctica

The Arctic ice is melting faster and faster, but now a research team thinks it has found a solution: artificial islands, huge pumps and underwater dams must stop melting.

The ice in the North Pole is melting at an alarming rate. That is why a research team from the University of Lapland in Finland has come up with technical projects to prevent glaciers from sliding into the sea and melting.

The researchers used the glacier at Pine Island in western Antarctica as an example. It slides away at a speed of 4 kilometers per year.

On the coast he loses his grip on the bottom, after which he goes out onto the sea like a big ice floe. He then begins to melt, and the researchers now want to stop that.

Three measures keep the ice cold

Several projects are meant to protect and stabilize the ice floe and curb the movement of the glacier.

The ideas range from pumping stations that have to pump the water layer under the glacier to submarine dams that prevent warm sea currents from coming into contact with the ice floes.

Expensive but necessary

According to the researchers, the projects only have to be implemented on a few routes along Antarctica and Greenland for a noticeable effect.

For example, 90 percent of the ice movement towards the coast of Antarctica runs via ice currents that are less than 100 kilometers wide. The same applies to 50 percent of ice migration on Greenland.

The scientists realize that the implementation of projects will be in the papers, but think that the costs outweigh what the world loses if we do nothing. According to various forecasts, the water level of the sea will have risen by 0.5 to 2 meters by the year 2100.

Dam must cool the ice

An underwater dam must ensure that the water around the ice remains cold. At the same time, the movement of the ice towards the sea is slowed down by an artificial island and by drilling.

Arnold gives climate skeptics a blow

Arnold Schwarzenegger is worried, very worried. About the environment. And Arnold is angry too. Angry at the climate skepticism, which is still prevalent in his new homeland, the US. A large part of the population is still convinced that global warming is a hoax. Terminator is not talking about it That's why the former governor of California and the dreamed future president of many moderate Republicans wrote an open letter to climate skeptics and deniers of global warming.

What does CO2 emit the most?

CO2 is emitted in all forms of incineration - from volcanic eruptions to the barbecue in your garden. But the amount of CO2 emitted by man has been increasing exponentially for some time, causing the natural ecosystems of the earth to become unbalanced. CO2 from fossil fuels such as oil and natural gas does not naturally belong in the atmosphere.
